Summary Introduction

To find: How a plant uses the sugar which they produce during photosynthesis to power their cells and some examples of cellular work.

Introduction: In photosynthesis, the chloroplast present in the leaves of the plant absorbed sunlight which is utilized to convert CO2 from air and water from roots into glucose and O2. Further glucose is utilized to make other substances like cellulose and starch and most importantly it is utilized in cellular respiration to make energy.

In cellular respiration, the mitochondria of both plants and animal cells break down simple sugar like glucose into CO2 and water and also release energy in the form of ATP. ATP is also known “energy currency” of the cell.

please draw!!! Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants. PLEASE INCLUDE , how does energy end up in the plant stem?
MAKE CONNECTIONS How do the CO2 moleculesused in photosynthesis reach and enter the chloroplastsinside leaf cells? (See Concept 7.2.)
For photosynthesis lab in biology 1) This lab uses spinach leaves. Name another plant that would make an interesting comparison to spinach. Explain why you think this leaf would provide an interesting comparison 2) The lights used in this experiment are 60W. What would you predict the effect of having stronger or weaker wattage bulbs would be on your results? Explain. 3)This lab uses 0.2% sodium bicarbonate. What would you predict the effect of raising or lowering the percentage would be on your results? Explain. 4)What are TWO other things that might be manipulated in an experiment using this same protocol other than the type of leaf, percent sodium bicarbonate, and wattage of light bulb? 5) What key thing do you have to look for on the graph to know for certain that your treatment has caused a significant effect?
